Hangtight Posted December 22, 2017 Share Posted December 22, 2017 Seeing as the only available TDC hop up for automatic guns that I'm aware of is not cheap and has to be imported from Canada, I thought I'd have a go at making my own. The base hop unit is from AirsoftPro, and is quite clever, but completely useless for R hopped barrels. So I've made a solid, concave nub that houses a tiny piece of urethane for some 'give', capped with a captive bar that the cam on the adjusting ring bears on. Let you know if it works.

Hangtight Posted December 24, 2017 Author Share Posted December 24, 2017 I shouldn't be surprised any more... Next installment once I've shortened the receiver end of an outer barrel by 4mm. Bloody Airsoft.... Link to comment Share on other sites More sharing options...
